3 Claims.

My invention relates to improvements in gasoline vaporizers. The invention primarily comprises a base member and a cap, the two being secured together and forming a vaporizing chamber. A fan is rotatably mounted within the chamber and supported upon a hub. The hub is supported on a hollow stem that communicates with a source of supply of oil vapors that are induced to flow through the stem and through the hub in which the bearing for the rotating member is disposed. The oil vapors flow through the bore of the hollow stem and lubricate the bearing of the rotating member disposed therein.

My invention is adapted for being placed between the carburetor and the intake manifold of an internal combustion engine, and the primary purpose and object of my invention is to promote vaporization of the fuel after the same leaves the carburetor. The hollow stem is adapted for connection to the crank case of the internal combustion engine and for drawing oil and other vapors therefrom, and liberating them in the'fuel mixture through my device.

Heretofore, it has been impracticable to place bearings within devices of this kind that would have a long life. Through theuse of my new and improved device the bearing is adequately lubricated thereby insuring its longevity.l The fan shaped rotating member is preferably made from at stock. The blades of the fan may be made in the usual and customary manner or they may be formed in a single piece without the separation of the edges of the respective blades thereby to require the passage of all of the vapors through perforations disposed within the respective blades. The blades are inclined to the horizontal and the holes are preferably placed therein when the disc from which 'the fan is to be made lies in a single plane. Thereafter the blades comprising the fan are offset from the common plane to place the holes out of alignment with the longitudinal center line of the fan. This causes a change of direction in the vapor passing through the holes at high velocity and rotates th-e fan because of the change in direction of the stream of vapor passing therethrough, This further increases the turbulence in the fuel stream and promotes more complete vaporization thereof.

The primary purpose and object of my invention is to more completely vaporize the fuel to be delivered into the intake manifold of an internal combustion engine. A further object of my invention consists in providing means for lubricating the bearing of the vaporizing member.

A still further object of my invention consists in so constructing the device that it will have a long and useful life and will have practical freedom from mechanical and operating annoyances.

On motors ofthe larger sizes where ample installation space is available; the device is, made as illustratedinFi'gs. l to 4 inclusive. When so made'the device is comprised of a base I. VA flange 2 is formed integr-al with the base and fastening holes 3 extend therethrough to-facilitate attachment to a fcompanion flange 4 as disposed upon a carburetor 5. A top 6 isprovidedhaving a ange 'I disposed upon one end and ailange 8 isdisposed. upon the opposite end. `The flange 8 is adapted'for attachment toa companion flange 9 formed integral with intake manifold IIJ.y The ,base I has a fiange IIv disposed upon its top end and complementary to the flange 'I and is secured thereto by suitable fastening screws i2 y A gasket I3 is placed between the complementary flanges 'l and Il to maintain a gas tight relationship therebetween.v A cross support I4 is formed' Yintegral with the base If A -hub' I5 is disposed within the top of the cross support and a suitable anti-friction bearing I6 is disposed therewithin. A passageway I1 extends longitudinally of one end of the cross support I4 and a threaded connection I8 communicates with the passageway I1 at its one end and with a piping connection I9 at its other end. The piping connection I9 leads to crank case 20 of in- -ternal combustion engine 2l.

A reservoir 22 is disposed within the hub and is in open communication with the passageway I1. A fan 23 is journaled in the anti-friction bearing I6. The fan as illustrated in Figs. 2 to 4 inclusive is comprised of a plurality of spaced blades 24. The blades have Vperforated spaced holes 25 disposed therein and extended therelations where space is restricted. In this form base 26 and top 21 are preferably made of noncorrodible metal. The base has an inwardly sloping wall 28 that is inclined substantially 54 degrees to the horizontal and the top 21 has an inwardly sloping side wall 29 that is inclined to the horizontal substantially 43 degrees. The base has a side wall 30 that is disposed at right angles to the end walls 3I and 32 of the respective to'p and base members. This forms an opening transversely through the base andtop that has similar terminal diameters and forms a bowl shaped space within which a fan 33 is rotatably disposed.

A hollow stern 34 extends transversely of the base and has a hub 35 disposed upon its inner end, the center of which is preferably placed to coincide with the longitudinal center line normal to the surfaces of the respective top and base members.

An anti-friction bearing 36 is disposed within the hub and carries a spindle 31 to which the fan 33 is secured by suit-able fastening means as through the use of a nut 38. The hollow stem 34 is placed in open communication with a source of oil vapor as the crank case of an internal combustion engine and in the normal operation of the engine the oil vapors are drawn through the anti-friction bearing 36 to lubricate it. An alternative fan structure is disclosed in Figs. 1l and 12. In this type, each of the varies of the fan has spaced holes 39 extending therethrough. These holes are preferably placed Within the disc prior to the formation of the vanes. Thereafter the varies are offset as illustrated in Fig. l2 and the adjacent edges of the respective vanes are secured together by webs 40. This forces practically all of the carbureted material to iiow through the spaced holes, and as in the forming of the vanes the holes are inclined at an angle to the axis of the fan, the material passing therethrough at high velocity causes the fan to rotate, increasing the turbulence in the vaporized fuel passing therethrough; and the holes being small further vaporizes the carbureted material and delivers the completely carbureted material to the intake manifold of the engine. The oil bearing crank case vapor flowing upward through the hub in which the rotating member is journaled maintains the bearing in a lubricated condition.

The cap is secured to the base as by suitable fastening screws 4I and 42 and the assembly is secured between the iianges of the carburetor and the intake manifold by suitable fastening means passing through holes 43 and 44 that are disposed longitudinally of the assembly. A suitable piping connection not here shown connects opening 45 disposed within the base to the crank case of the internal combustion engine.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.
